5.7 R/T TT build

I'm looking for a little advice here. I am dropping my 2013 R/T Automatic off this Friday for a pretty substantial build. I have three options and I'm wondering what the best bang for the buck will be.

I have an estimate for a twin turbo set up with a new fuel system, boost controller and methane injection. I have another with the same and then adding forged internals thus increasing the boost/HP. And finally I'm beginning to think about doing a 392 stroker forged internals and the same TT kit. Obviously I know which one will make the most power but I'm wondering if it's worth the money.

This car will not be on the strip, this is currently a daily driver but will become a weekend toy after this build. I have never owned a car with 600-700HP so I'm sure that it will blow me away regardless of which build I choose.

Before you start telling me to sell the car and buy a Hellcat/Scat Pack, I love this car, I love the way it looks. I have gotten more compliments on this car than any car/truck I've ever owned. I want THIS car but I want it to embarrass any and all Camaros and Mustangs that pull up next to me (I know there is always someone faster).

I'm also VERY concerned about putting that much power to the ground. I already have a hard time hooking up on the current tires (Nitto Motivas). I want this baby to look like a lowly stock R/T so that all these EVOs and STIs and Mustangs.......get a nice shock when I grow very small very quickly. Just wondering if anyone has a similar build and what they wish they had done differently. Thanks!!

So here are the specifics:

PT6266 GEN2 CEA with Ball Bearing upgrades
Forged Crank, Rods and Pistons
All ARP Bolts
Head Studs
GReddy ProFec Boost Controller
JBA Headers 1965SJT
Diablo i2010
Dyno Street Tune
ID1000 injectors
Meth kit - M15 nozzle, 3 gal vortech
NGK Iridium spark plugs
LX/LC/LD L3 Fuel System
Walbro GSS342 primary
TI Auto F9000002667 secondary

This is so funny to me, I'll be doing the exact same thing with my 13 Challenger, going with a Hellion tuner kit though. No telling you to sell anything from me. I can tell you that turbos don't care rather what the short block is. They spool and blow air no matter what. That being said, I'd go with forged internals just to stay on the safe side when it comes to running boost. Before I purchase the kit for my ride, I'll be strengthen my suspension and clutch to handle the power I intend to make. I'll have to do my build over time, and myself due to wife and kids. Just found out I have another on the way. Fun times in my world right now. Good luck with the build, and please let me know how happy you end up with the car when you are finished. If it is anything like I envision I'm sure you will love it. Lastly I applaud you for building your ride, as oppose to buying a Hellcat (not that there is anything wrong with that route). I firmly believe when I finish with my R/T it can be faster than a Hellcat for much less money spent. Take care and good luck to you with your build.

Ok well the car is dropped off. Looks like I'm not gonna go with forged internals YET........ Might change my mind before all is said and done. I did add the new loudvalves to the build. I am sitting in Iraq for the next 9 months while the build is happening. I can't wait to get back and watch the 392, Camaro SS and Mustang drivers scratching their heads as I disappear into the distance!!

You can only run about 7-8 psi on non forged internals. So you may make 550hp tops. You forge it, then turn the boost up to 12psi and start making much more power.

Yeah I know, and believe me I go back and forth on it everyday. I'm really tempted to get a forged 392 stroker kit and then turn up the boost and HOLD ON!!! I'm trying to keep the build cost semi-reasonable but then, WTH, it's only money, they print more everyday.

When you go with the forged 392 stroker, will you be buying the kit or having a shop do the build? Don't you need to have oil squirters machined into the block when you go with a 392 stroker?

Anyone from middle Tennessee will probably be familiar with the shop, it's DBR High Performance. The engine is out and will be sent to his Mopar engine expert for the forged 392 build, to include high flowing heads and a cam that is designed for forced induction. I won't be back from Iraq until Jan-Feb 2017 so there is no rush. Going to have plenty of time to build it correctly. I'm still toying with the idea of building the tranny as well. Very excited about the build, but the price keeps going up, lol. Guess that's the cost of HP and fun. And I have no idea why the forum rotated the pics when I uploaded them, oh well.

Good luck on the build. You're also going to need half shafts to keep the power down. What are you looking to run on low boost? Plus, tuning these cars for twin turbos will be a major pain in the butt so who is going to tune it? There's a reason why so many people go supercharged but you have the same idea that I do. I would love to twin turbo my Challenger but the tuning has me concerned about it as these cars lean out under partial throttle.

I love American muscle cars like a thrice-divorced 45-year old tax attorney loves barely legal coeds. That is to say; passionately, inappropriately and almost certainly inadequately while muttering whispered apologies to the beautiful thing I am probably ruining forever.

To those who call me crazy: the difference between genius and insanity is measured only by success.
